Renewed July 29, 1936 33 Claims.

This invention relates to improvements in brake rigging for railway car trucks of the beam type having associated therewith that type of brake known as the clasp brake, in which brake shoes are applied to opposite sides 'of each car wheel.

It is an object of this invention to provide a brake mechanism of the so-called beam type, in cylinder or other actuating means is mounted on or carried by the truck frame.

It is a further object of the present invention to provide such a brake mechanism with a novel arrangement of an automatic slack adJuster :Lhich will compensate for the wear of the brake oes.

A still further object of the present invention is to equip such a system of brakes with a. manual slack adjuster to compensate ior wheel wear.

Itis another obiect'of the present invention to extend the pull rod connecting each pair of live andv dead truck levers through a. bracket fixed to the truck frame, thereby preventing lateral displacement of the live truck lever.

Still another object of the present invention is ,to provide an improved arrangement of balance hangers for the inside brake beams.

With these and various other objects in view, the invention may consist 'in certain novel features'of construction and operation as will be more fully described and particularly pointed out in the specification, drawings and claims appendedhereto.

In the drawings- Flgure l is a fragmentary plan view of a railway car truck emb dying the features of the present invention:

Figure 2 is a side elevation of the arrangement shown in Figure 1;

Figure 3 is a fragmentary sectional view taken in the plane as indicated by linel-l of Figure hand Figure 4 is a fragmentary end elevation.

This application is a continuation-impart of application Serial No. 602,705, filed April 2, 1932.

Brake rigging of the present invention is shown ,as applied to a four-wheel truck comprising a truck frame It and wheels ii. The wheels are engaged on either side by inner brake shoes l4 and outer brake shoes i5. Brake heads It are supported by a ,brake beam 20 which in turn is carried by brake hangers I2 pivoted at 24 upon brackets hated to end transoms of the frame -iil. 'The inner brake shoes H are supported by brake heads 2 carried by the ends of an inside brake beam 80 which in turn is carried by brake hangers 82 pivotally connected at 14 to brackets 35 fixed to the irame i0. Additional central bal' ance hangers 88 are provided for the inside brake beams pivotally connected at 40 to brackets 42 fixed to the truck frame I ii. The brake beams 30 are provided with fulcrums 44 for pivotal connection at 46 to the lower end of each of the hangers 38. These inside balance hangers are disposed in the positions shown to reduce the length of the balance hanger brackets 42.

The dead truck levers 48 are fulcrumed at their upper ends 50 by a pivotal support upon brackets 52 fixed to the ends of the frame It. The levers 48 are connected at their lower ends 54 by fulcrums 56 to the outside brake beams 20. Live truck levers 58 are connected at their lower ends 50 by fulcrums 62 to the inside brake beams'SO. The truck levers associated with each wheel are connected by pull rods 54 pivotally connected at 0 56 to the dead truck levers intermediate the ends thereof, and pivotally connected at E8 to the live truck levers also intermediate the ends thereof. Each pull rod 64 is extended as at 69 beyond the live truck lever and has sliding cooperation with a slotted opening ill formed in a guide bracket 12 fixed to the frame I 0, the guide so formed being substantially of inverted U-shape. It will be understood that by guiding the pull rod in this manner lateral displacement of the live truck levers is prevented.

The upper ends 14 of the live truck levers 58 are pivotally connected by links 16 to the inner end ll of a live cylinder lever 80 and theinner end '2 of a dead cylinder lever 84, respectively. The outer end 86 of the live cylinder lever is connected to the piston rod 88 of the cylinder unit III which is carried by the bracket 92 upon the frame It. The dead cylinder lever 84 is connected at its outer end 84 to an automatic 4o slack adjuster device 86. The cylinder levers 80 and 84 are pivotally connected intermediate their ends by pull rod 98 provided with a manual slack adjuster IN. The outer end of the live cylinder lever an may be additionally and slidably supported on brackets I02 and I04 fixed to the frame i0.

Itistobeunderstoodthatldonotwishtobe limited by the exact embodiment of the device shown. which is merely by way of illustration and not limitation, as various other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention as ascertained from the scope of the appended claims. 66
